WebFilters and ultra lters The notion of a lter resp. an ultra lter is a powerful tool both in set theory and in topology. The importance of ultra lters in these notes lies in the fact that the set Sof all ultra lters on a xed semigroup Scan be made into a compact right topological semigroup which will be our central object of study. WebIf Z and e are two filter bases, we say that Z is a refinement of e3 if every set in e contains some set in Z. If this is true, we write ZDQ3. It is readily seen that if Z)DQ3 and if 05 and a are the filters they generate, then (Da both in the sense we have just defined for filter bases and in the sense that every set in a is also in 5.

WebTo filter a topology, you supply a ring filter function to filter. The filter function is invoked for each ring in the input topology, being passed two arguments: the ring, specified as an array of points where each point is a two-element array of numbers, and the interior flag. WebFilters vs nets in topology. Nets are a natural generalization of sequences in arbitrary topological spaces. Using the language of nets we can extend intuitive, classical sequential notions (compactness, convergence, etc.) to arbitrary spaces.
